217 °C

Additional information

In a non-GLP boiling point study conducted in accordance with standardised guidelines, the boiling point of the test substance was determined using the Siwoloboff method. Under the conditions of the test, the boiling point of (R)-2,2,3-trimethylcyclopent-3-ene-1-acetaldehyde was determined to be 217ºC (491 K). As the study was performed in line with standardised guidelines, it is considered to be the key study for this endpoint and was assigned a reliability score of 1 in accordance with the principles for assessing data quality as set out by Klimisch (1997).

The published handbook entry was assigned a reliability score of 2, in accordance with the guidance document published by ECHA, May 2008, Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance and using the principle for assessing data quality as set out by Klimisch (1997), which instruct that data from a peer reviewed database where the information of the peer review process is available, may be considered reliable with restriction. The origin and quality of data from the two safety data sheets could not be assessed, the data was therefore assigned a reliability score of 4 (not assignable) using the principle for assessing data quality as set out in Klimisch (1997). The boiling point values were reported to be 60 -78ºC at 10-105 mmHg.
